MAT_VARGETSTRUCTSLINEAR(3) Library Functions ManualMAT_VARGETSTRUCTSLINEAR(3) NAME Mat_VarGetStructsLinear -- Linearly index a structure variable SYNOPSIS #include <matio.h> matvar_t * Mat_VarGetStructsLinear(const matvar_t *matvar, int start, int stride, int edge, int copy_fields); DESCRIPTION The Mat_VarGetStructsLinear() function selects a subarray from a struc- ture array matvar. Each of the elements in the subarray contains all of the fields of the structure. The indexing starts at the start element in the array (0 being the first element), and reads every stride values (1 being every element, 2 every other element, etc.). The total number of elements in the subarray is specified as edge. The original array must have at least start+(stride-1)*edge+1 elements. The copy_fields option specifies whether the fields of the original structure are copied for the new subarray. If set to 0, the returned structure ar- ray's fields have the same pointer as the original array, and the data field of the subarray structure. The subarray is marked with the con- serve memory flag indicating that the fields should not be free'd. They are free'd when the original structure is free'd. RETURN VALUES A subarray of the original structure array, or NULL if there is an er- ror. SEE ALSO Mat_VarGetStructs(3) FreeBSD Ports 14.quarterly March 14, 2012 MAT_VARGETSTRUCTSLINEAR(3)
